After researching the potential side effects of Tylenol (acetaminophen), I found that stomach trouble is not listed as a common side effect. However, it's important to note that any medication can cause side effects, and some people might experience mild digestive issues when taking Tylenol.

Common side effects of Tylenol include headache, nausea, and loss of appetite [1]. In rare cases, Tylenol can cause severe side effects such as allergic reactions, dark urine, and yellowing of the skin or eyes [1].

It's always recommended to follow the dosage instructions on the label and consult with a healthcare professional if you have any concerns about taking Tylenol or experience any unusual symptoms [1].

If you have a history of stomach problems or are taking other medications, it's essential to consult with a healthcare provider before taking Tylenol to ensure it's safe for you [2].

In summary, while stomach trouble is not a common side effect of Tylenol, some people might experience mild digestive issues. If you have any concerns or experience unusual symptoms, consult with a healthcare professional.
